1.OUPUT參數返回值

復制代碼 代碼如下:

CREATE PROCEDURE [dbo].[nb_order_insert](
@o_buyerid int ,
@o_id bigint OUTPUT
)
AS
BEGIN
SET NOCOUNT ON;
BEGIN
INSERT INTO [Order](o_buyerid )
VALUES (@o_buyerid )
SET @o_id = @@IDENTITY
END
END

復制代碼 代碼如下:

DECLARE @o_buyerid int
DECLARE @o_id bigint
EXEC [nb_order_insert] @o_buyerid,@o_id output

復制代碼 代碼如下:

CREATE PROCEDURE [dbo].[nb_order_insert](
@o_buyerid int ,
@o_id bigint OUTPUT
)
AS
BEGIN
SET NOCOUNT ON;
IF(EXISTS(SELECT * FROM [Shop] WHERE [s_id] = @o_buyerid ))
BEGIN
INSERT INTO [Order](o_buyerid ) VALUES (@o_buyerid )
SET @o_id = @@IDENTITY
RETURN 1 ― 插入成功返回1
END
ELSE
RETURN 0 ― 插入失敗返回0 END

復制代碼 代碼如下:

DECLARE @o_buyerid int
DECLARE @o_id bigint
DECLARE @result bit
EXEC @result = [nb_order_insert] @o_buyerid ,o_id output

復制代碼 代碼如下:

CREATE PROCEDURE [dbo].[nb_order_select](
@o_id int
)
AS
BEGIN
SET NOCOUNT ON;
SELECT o_id,o_buyerid FROM [Order]
WHERE o_id = @o_id
GO

（1）、使用臨時表的方法

復制代碼 代碼如下:

CREATE TABLE [dbo].[Temp](
[o_id] [bigint] IDENTITY(1,1) NOT FOR REPLICATION NOT NULL,
[o_buyerid] [int] NOT NULL
)
INSERT [Temp] EXEC [nb_order_select] @o_id
